Came across a large range of consulting tools following a link from Headshift:

Thanks to Martin Leith for putting all of this content online. It supports my argument that more consulting firms should make their methodologies public. I am convinced that the "what to do" piece is easy to tell someone else, and is not damaging to make public, as the "how to do it" piece is by far the most complicated and value-adding. Even talented consultants would find it difficult to apply (e.g.) Martin’s methods without some training.
